Answer 2

Verified answer

Hola! :3

Recordemos la fórmula de la "Diferencia de cuadrados":

(a + b)(a - b) = a² - b²

Entonces:

a) (x + 1)(x - 1) = x² - 1²

(x + 1)(x - 1) = x² - 1

b) (x + 2)(x - 2) = x² - 2²

(x + 2)(x - 2) = x² - 4

c) (x + 3)(x - 3) = x² - 3²

(x + 3)(x - 3) = x² - 9

d) (x + 4)(x - 4) = x² - 4²

(x + 4)(x - 4) = x² - 16

e) (x + 5)(x - 5) = x² - 5²

(x + 5)(x - 5) = x² - 25

f) (x + 6)(x - 6) = x² - 6²

(x + 6)(x - 6) = x² - 36

Espero haberte ayudado :D
